What you get#
Onekey exposes USGS as 6 endpoints behind one API key: 3 endpoints return one record (data is an object) and 3 endpoints return a list (data is an array). Every answer uses the same envelope (success, data, metadata, error), the cost is reported in metadata.credits_charged, and fields are mapped onto the unified schema so the code you write for USGS also works for the rest of the maps, weather & space category.
Endpoints#
| Endpoint | What it does | Parameters | Credits | Status |
|---|---|---|---|---|
earthquake | One USGS earthquake event by id. | id* | 1 | stable |
earthquake_count | Count of earthquakes at or above a magnitude since a date. | start*, minmagnitude | 1 | stable |
earthquake_search | Search earthquakes (FDSN query): minimum magnitude, newest first. | limit, minmagnitude | 5 | stable |
earthquakes | Recent earthquakes from a USGS summary feed (e.g. 2.5_day, significant_week). | feed | 5 | stable |
earthquakes_near | Earthquakes within a radius of a point (FDSN query), newest first. | lat*, lon*, radius_km, limit, minmagnitude | 5 | stable |
streamflow | Latest instantaneous streamflow (discharge) for a USGS gauge site. | site*, parameter | 1 | stable |
A * marks a required parameter. Each endpoint name links to its reference page with the full parameter table, caching window and a recorded response.

This calls usgs.earthquake (1 credit, stable). Replace YOUR_API_KEY with your key; sign up, no card. 1,000 free credits cover the open-platform endpoints. Hard-to-reach platforms (X, TikTok, Instagram, Reddit, and others marked on their page) need a verified email and a purchased pack.

-H "x-api-key: YOUR_API_KEY"Fields you get back#
These unified fields come back from USGS, with the same names as on every other platform. The count is how many of its 6 mapped endpoints return the field; a field the source lacks is null, never missing. 12 platform-specific fields (ext.<name>) come on top, documented on each endpoint page.
| Field | Type | Endpoints |
|---|---|---|
place.lat | number | 5 |
place.lon | number | 5 |
content.createdAt | ISO 8601 date | 4 |
entity.category | string | 3 |
entity.date | ISO 8601 date | 3 |
entity.id | string | 3 |
entity.name | string | 3 |
content.id | string | 2 |
content.title | string | 2 |
content.url | URL | 2 |
entity.description | string | 2 |
entity.url | URL | 2 |

Pricing#
USGS calls cost 1 to 5 credits, flat per endpoint. Free when served from cache (0.2 credit for a cached response over 100 KB). Invalid, failed or not-found calls are not charged. See pricing for credit packs.
